MBP wont connect with external monitor

post #1 of 3
Thread Starter 
Hey guys, so i picked up a mini display port -> DVI adapter for my 13.3 MBP...

I plugged in the mbp to my monitor, and the screen on the mbp goes blue for a second.. then back to normal... I set it to mirror the display.. but my monitor just stays in sleep mode and doesn't detect that anything is connected to it, yet my MBP see's the display connected as a 'Syncmaster".. which it is...

help??!

Thanks

Make sure your OS X is updated, go to System Preferences > Display > Detect Displays > and instead of mirror try extend and see if it works.

Most likely a faulty cable. Had this happen with my MBP and I tried everything and it turned out to be the cable.
